able stra s I secure a. rack B' engagingwitha pinion which pinion is tna spindle C,

Patented March 20, 1906. 1902. Serial No. 138.661.

upon which spindle is mounted the Wheel 0 the left the carriage of theadding-machine will move to the right.

For the purpose of limiting the rotation of the adding wheels,hereinafter to be described, and determining the position in which theyshalll stop rotation and register the desired figures I arrange a nestof ins, preferably in six columns, each column avmg nine, one above theother, the number of columns depending upon the number of adding-wheelsemployed. I therefore show anest Lin Figs. 2, 15, 16, and 17,in whichthe pins K, arranged to be operated upon, are illustrated. For thepurpose oi arranging for operatin the desired pins K contained in thenest L,I arrange in the carriage J a series of pins P, similar to thepins K, in such a manner that when one of the pins P is pressed in, asshown in Figs. 2 and 15, a corresponding pin K of the nest L will bepressed forward within the path of the shoulder m on the end of the rackM, as shown in Figs. 2 and 15.

For the purpose of operating the pins P and causing them to act upon thepins K for the purpose of projecting the said pins K into the path ofthe racks M, I arrange a series of narrow thin plates or rods E,extending across the adding-machine from one side to the other, each ofsaid plates E supported and operated by the arms E, said arms mounted'upon rods G, said rods supported in posts 9, attached to the sides ofthe machine, res ectively, each of said arms E 'provided Witliprojections extending to the rear of said posts g, said projectionsconnected, by means of links g, to pivoted levers O, which pivotedlevers are acted upon by the keys of the type-writing machine, ashereinafter more particularly described. It will be understood that inthe device as illustrated there are nine plates E and nine rods G, suported as shown in Fig. 2. As thus mounte when the bars of thetype-writingrnachine which indicate the numbers desired are de ressedthe corresponding arms E will be acte upon,

causing the plate E, to engage with the correthe pm is presse on by oneo the plates E 7 O, and Oipreferably. O is a pin in the ,in the shoulderm. Pin 0 is p'zaced in the v and is attached to the handle -N in suchla6o 1 1 against the tension of the spring V, the spring Qbeing raised bysaid movement of the -seg- 'ment.

1 The racks M engage .with the segment 9, mounted on .the spindlecarrying the addingpear on the paper. The type-writing mathe springwillbe compressed, and after pressure has ,een removedthe pin under theinfluence of the spring will be restored to its normal osition.

range on the carriage a flange Z in such a manner that'as the carriage,is returned the 4 flange I will press back each of the pins K whichhave-been forced by the pins P into the path of the rack-shoulder m.-For the purpose of holding the rack M v in position with its shoulder mbelow the nest of pins L, I arrange a series of three pins blockcontaining the nest L (shown in Figs.

- t .2, 15, and 17) and which normally extends into the shoulder 'm atthe end of therack M,

as sh'o wnvin Fig. 17. O is'a short pin placed carriage J in the rear ofthe racks M. I preferably arrange a spring 0 on the pin 0 adapted toreturn the pin 0 to its normal position after having been operated upon.

It is a parent that before the rack M can be move' it is necessary todrive out pin 0", which holds the rack in position below the nest L. Toaccomplish this result, I have arranged a lever O,- properly fulcrumedat one end thereof beneath the rear of the rack M, the'otherend adaptedto be operated on by the keys of the ty e-writingma'chine. 3 I mountthe. bell-cran lever 0 preferably above and in the same vertical planeas is the pivoted end of the lever O, as shown in Fig. '2. One arm ofthe bell-crank lever is attachedto the lever O. The other arm isprovided with a fingerat its end and arranged to engage with the pin OAs thus constructed and mounted up when the lever O is actedtupon by thetype-writing machine the pin 0 acts upon the pin 0? in the shoulder m ofthe rack M and forces the pin 0 out of said shoulder, and thereforeliberates the rack M. In order to drive back the pin 0 and the 'pin 0 Iarrange on the carriage J a flange j, which, with the return movement ofthe car riag'e, will force the pins 0, and therefore the pins 0 intotheir normal position.

The racks Mare respectively connected preferably with the segmentalwheels .-7 by means of spiral springs V. Each segment is,"

preferably provided with a groove 8, within which the spiral spring Vengages. Each segment of the wheel 7 is mounted on rod Z manner that bythe movement of the handle the segment Will be partially rotated,whereby the rack M will be moved vertically wheels W. on the face of these ment 9 adjacent to the Wheel W is mounte the dog 10, which engageswith the teeth of the annular rack 10 on the face of the wheel W. Thedog is so placed in' reference to the teeth of the rack 10 that as therack M moves pward under the influence of the segment-wheel 7 it rackand cause the wheel W-to rotate. As the extent of the rotation of thewheels W-is raised, it is apparent that the location of the mine theposition in which the wheel -W will be atthe end of its revolution. Thefigures place of registration 'will correspond with the figures on thekeys of the type-Writer which were operated on and by which operationpins K are placed in the path of the shoulder m of the rack M.

In order to provide for the carry which hundred, &c., requiring the nextwheel; on the left to add one for the carry, I place on the face of thewheel W, adjacent tothe next cry of the wheel to which it/is attached. Imount a latch 12 adjacent to and between the wheels, respectivelyprovided with a projection 13, which will engage with the lift 11wheuthe wheel W has reached the zero on the periphery. The projection 13on the latch 12 when ite ngages with the lift 11 will raise thelatch/and liberate a pin 14 on the bell-crank lever 15, which is held inconnec-l latch 12. -The bell-crank lever 15 carries a pawl 18 whichengages with the teeth on the periphery of the next adjacentadding-wheel on the left. When the latch 12 is lifted un; der theinfluence of the lift 11 and the bell crank lever is liberated, the pin14 coming out of engagement with the latch 12,- the sprin 17,/ attachedto said bell-crank lever, move th'e bellcrank lever, and therefore thepawl 18, forward, and thus move the wheel with which the pawl 18 engagesone-space, which will make the carry. In order to reset the bell-cranklever 15 in contact with the the bell-crank lever 15 has one of its armswithin the path of the segment-wheel 7, and as the handle N, attached tosaid se mentlever will be pushed forward' against the tension of thespring 17, and the pin 14 will engage with the projection 16 on'thelatch' 12 and will be held in position thereby until the latch 12 isoperated again b the lift-11.

The operation of my macl iine is as follows:

I strike the keys on the type-writer correlimited by the height to whichthe rack M ispins K, forced out of the nest L, will deter-.

on the periphery of the adding-wheel in the sponding to' the figureswhich I wish to ap- I .will engage with the teeth of the annular takes,place when .the addition passes ten,

adjoining adding-wheel, a lift ll ina position adjacent to thezero-pointon the periphtion-therewith by the'projection 16 on the latch12, and thus prepare for the next carry,

wheel, is operated the arm of the bel -crank chine will print thefigures in the usual manner. As the differentkeys are struck the pine Pcorresponding thereto in the carriage .time each of the pins in theshoulder m will be driven in and retaining-pins O driven out of contactwith the said shoulder on the the end of the rack, thus releasing eachrack within the path of which one of the pins from the nest has beenprojected, each of the other racks being held by their retaining-pins,respectively. The handle N is drawn forward and downward by theoperator. Theseg ment-whee'ls7 are consequently rotated, and the racksthat are released are raised as far'as they can go, being stopped,respectively, by pins K, which have been projected into the ath of theirmovement. The result will be t at each of the wheels will be stopped inthe position which will bring the numbers on their peripheriescorresponding with the numbers struck on the keys of the type-writmgmachine in the place of registration im- Inediately before theoperator.- It will be noticed that in the movement of the handle a Nall,of the segment-wheels 7 will be caused to rotate, but not all oftheracks will be raised, for the reason hereinbefore stated, the spiralspring V, attached to each rack, permitting of this movement of thesegmentwheels when the racks are held stationary. In order to place theracks in their normal position readv for the next operation of the mahine, I release handle N. The racks will fall back, the shoulders willbe returned immediately and secured in their places by means of. thepins which will by the movement-of the carriage be forced into positionwithin thc shoulder, and thejmachine be readyfor operation. When thenext line of figures is placed beneath the first, the operation isrepeated, and the additionthat is, the sum of the two lines offigureswill be recorded on the face of the wheels.

For the purpose of t-abulating I have arranged in the rear of the addingdevice a series of columnating rods 21, which are arranged, verticallyand normally held elevated by a series of springs 22. Each rod isprefera ly provided with a spring, one end of which spring rests uponthe frame of the machine and at the other end engages with the lowerportionof the enlarged head of the rod. Extending across from one sideof the series of tabulators to the other I arrange a bar 23, which is soplaced in reference to the columnating rods 21 that when the said rodsor any of them are depressed, as is shown at the extreme left of Fig.20, the enlarged head of the rod will engage with the bar 23 and drawthe bar downward, For this purpose I may have the bar 23 placed on therods 21-that is, the 'rods may be passed through suitable openings inthe bar. The bar 23 is connected nating-rod 21.

ing'machine, as shown by dotted lines in Fig.

1. Thus when the lever 24 is operated by the bar 23 the arm 25 will beraised, which will raise the type-writer rack 26 out of connection withits actuating-pinion (not shown) and will free the carriage, which willimmediately under the tension of the springs actuating it be caused. tomove, the direction of the movement of the adding-device carriage beingshown by arrow in Fig. 20. The adding-machine carriage will be stoppedin its movement by the end of the depressed colum- By this means theadding mechanism will be set so that the figures registered by thetype-writing machine shall be in their proper position. It isunderstood, of course, that the colunmating-rods may be acted upon asoccasion requires and that after they have been depressed they will,under the influence of the springs 22, be returned to their-normalposition.
